Accompanying drawing explanation
Fig. 1 is the structural representation of the embroidery machine thread take-up lever structure of the utility model embodiment.
Detailed description of the invention
Set forth a lot of detail in the following description so that fully understand the utility model.But the utility model can be much different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
Please refer to Fig. 1, for the structural representation of the embroidery machine thread take-up lever structure of the embodiment of the present invention, comprise: stepper motor 10, the bar linkage structure that three connecting rods are formed, fix plate 31 and thread take-up tension lever 30, described bar linkage structure comprises first connecting rod 21 successively, second connecting rod 22 and third connecting rod 23, described stepper motor 10 drives first connecting rod 21, and drive second connecting rod 22 and third connecting rod 23, described fixing plate 31 is articulated on a fixed pin shaft 33, one end of described third connecting rod 23 is connected with fixing plate 31, described third connecting rod 23 makes described fixing plate 31 can rotate around fixed pin shaft 33, described fixing plate 31 also fixes with one end of thread take-up tension lever 30, make described thread take-up tension lever 30 can with fixing plate 21 synchronous axial system.
In the present embodiment, described first connecting rod 21 is holes connecting rod, the hole being positioned at first connecting rod 21 one end is fixed by a hole of bearing pin and second connecting rod one end, another hole and stepper motor 10 driving shaft that are positioned at first connecting rod 21 fix, described stepper motor 10 is utilized to drive first connecting rod 21, first connecting rod 21 is rotated, and drives second connecting rod 22.Described second connecting rod 22 is holes connecting rod, described third connecting rod 23 is three hole connecting rods, a hole of described second connecting rod 22 other end is fixed by a hole in the middle of bearing pin and third connecting rod 23, a hole of one end of described third connecting rod 23 is articulated on a bearing pin fixed, described fixing plate 31 has a breach, the other end 25 and the breach clamping fixing plate 31 of described third connecting rod 23.
In the present embodiment, described thread take-up tension lever 30 by three bolts 32 by one end of thread take-up tension lever 30 with fix plate 31 and fix, after described fixing plate 31 is driven to rotate, described thread take-up tension lever 30 also can synchronous rotary, thus thread take-up tension lever can bob.
In the present embodiment, described stepper motor 10 is independent mutually with the motor of driving shank, and described stepper motor 10 is all connected with the control unit of embroidery machine with driving the motor of shank, utilize the stepper motor 10 of the corresponding shank of control unit Synchronization Control and drive the motor of shank, make thread take-up tension lever 30 and shank can realize synchronous working, to change when driving the anglec of rotation of motor of shank or the cam face of correspondence changes, when the change of framework demand line amount is large, the anglec of rotation of corresponding stepper motor 10 changes, the amplitude of thread take-up tension lever 30 bob is caused to become large, floss silk remains balanced tension force, accordingly, to change when driving the anglec of rotation of motor of shank or the cam face of correspondence changes, when the change of framework demand line amount is large, the anglec of rotation of corresponding stepper motor 10 changes, the amplitude of thread take-up tension lever 30 bob is caused to diminish, the biography string holes of thread take-up tension lever and the stitch length of corresponding embroidery machine syringe needle are steady state value substantially, and positive negative error is no more than 3mm, and embroidery machine can not break.
In the present embodiment, a machine head of embroidery machine generally includes multiple thread take-up tension lever 30, described multiple thread take-up tension lever 30 is in word order, described stepper motor, bar linkage structure are arranged in a travel mechanism, described travel mechanism comprises the second stepper motor and guide rail, and described stepper motor, bar linkage structure move forward and backward along the orientation of multiple thread take-up tension lever.
In the present embodiment, because described thread take-up tension lever has rebounding mechanism, when thread take-up tension lever does not work, the multiple thread take-up tension levers being positioned at one, same machine all recoil to initial position, the gap position of the fixing plate that each thread take-up tension lever is corresponding is identical, therefore the fixing plate that each thread take-up tension lever is corresponding can form scalloped channels, and described scalloped channels allows the other end 25 slide anteroposterior of third connecting rod 23 just.The scalloped channels of plate formation is fixed by each, the other end 25 of described third connecting rod can slide into the gap position of wherein any one fixing plate, and Driving Stepping Motor controls the thread take-up tension lever of correspondence position, owing to only needing a stepper motor just can control thread take-up tension levers whole on a head, cost is lower.
Because the rotational angle of stepper motor can change along with the change of style version band stitch length, thread take-up tension lever conveying and exhausting line amount, also along with change, are conducive to improving high speed, reduce outage.Meanwhile, by changing thread take-up tension lever conveying and exhausting line amount, reaching various embroidery effect, enriching anglicanum, added value of product is provided.
Because existing driving thread take-up tension lever all adopts cam to drive, the utility model solves the problems such as difficult, the easy damage of existing engineered plastics material cam cutting, reduces maintenance cost.
Meanwhile, because described stepper motor is independent mutually with the motor of driving shank, greatly can reduces spindle load, improve the dynamics of machine.
Although the utility model with preferred embodiment openly as above; but it is not for limiting the utility model; any those skilled in the art are not departing from spirit and scope of the present utility model; can make possible variation and amendment, the scope that therefore protection domain of the present utility model should define with the utility model claim is as the criterion.
